6 bluetooth_helper_selinux - Security Enhanced Linux Policy for the blue‐
7 tooth_helper processes
8
10 Security-Enhanced Linux secures the bluetooth_helper processes via
11 flexible mandatory access control.
12 The bluetooth_helper processes execute with the bluetooth_helper_t
14 SELinux type. You can check if you have these processes running by exe‐
15 cuting the ps command with the -Z qualifier.
16 For example:
18 ps -eZ | grep bluetooth_helper_t
20
24 The bluetooth_helper_t SELinux type can be entered via the blue‐
25 tooth_helper_exec_t file type.
26 The default entrypoint paths for the bluetooth_helper_t domain are the
28 following:
29 /usr/bin/blue.*pin
31
33 SELinux defines process types (domains) for each process running on the
34 system
35 You can see the context of a process using the -Z option to ps
37 Policy governs the access confined processes have to files. SELinux
39 bluetooth_helper policy is very flexible allowing users to setup their
40 bluetooth_helper processes in as secure a method as possible.
41 The following process types are defined for bluetooth_helper:
43 bluetooth_helper_t
45 Note: semanage permissive -a bluetooth_helper_t can be used to make the
47 process type bluetooth_helper_t permissive. SELinux does not deny
48 access to permissive process types, but the AVC (SELinux denials) mes‐
49 sages are still generated.
50
53 SELinux policy is customizable based on least access required. blue‐
54 tooth_helper policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run bluetooth_helper with the
56 tightest access possible.
57 If you want to allow users to resolve user passwd entries directly from
61 ldap rather then using a sssd server, you must turn on the authlo‐
62 gin_nsswitch_use_ldap boolean. Disabled by default.
63 setsebool -P authlogin_nsswitch_use_ldap 1
65 If you want to allow all domains to execute in fips_mode, you must turn
69 on the fips_mode boolean. Enabled by default.
70 setsebool -P fips_mode 1
72 If you want to allow confined applications to run with kerberos, you
76 must turn on the kerberos_enabled boolean. Enabled by default.
77 setsebool -P kerberos_enabled 1
79 If you want to allow system to run with NIS, you must turn on the
83 nis_enabled boolean. Disabled by default.
84 setsebool -P nis_enabled 1
86 If you want to allow confined applications to use nscd shared memory,
90 you must turn on the nscd_use_shm boolean. Enabled by default.
91 setsebool -P nscd_use_shm 1
93 If you want to allow regular users direct dri device access, you must
97 turn on the selinuxuser_direct_dri_enabled boolean. Enabled by default.
98 setsebool -P selinuxuser_direct_dri_enabled 1
100 If you want to allows clients to write to the X server shared memory
104 segments, you must turn on the xserver_clients_write_xshm boolean. Dis‐
105 abled by default.
106 setsebool -P xserver_clients_write_xshm 1
108
112 The SELinux process type bluetooth_helper_t can manage files labeled
113 with the following file types. The paths listed are the default paths
114 for these file types. Note the processes UID still need to have DAC
115 permissions.
116 bluetooth_helper_tmp_t
118 bluetooth_helper_tmpfs_t
121 user_fonts_cache_t
124 /root/.fontconfig(/.*)?
126 /root/.fonts/auto(/.*)?
127 /root/.fonts.cache-.*
128 /home/[^/]+/.fontconfig(/.*)?
129 /home/[^/]+/.fonts/auto(/.*)?
130 /home/[^/]+/.fonts.cache-.*
131 xserver_tmpfs_t
133
137 SELinux requires files to have an extended attribute to define the file
138 type.
139 You can see the context of a file using the -Z option to ls
141 Policy governs the access confined processes have to these files.
143 SELinux bluetooth_helper policy is very flexible allowing users to set‐
144 up their bluetooth_helper processes in as secure a method as possible.
145 STANDARD FILE CONTEXT
147 SELinux defines the file context types for the bluetooth_helper, if you
149 wanted to store files with these types in a diffent paths, you need to
150 execute the semanage command to sepecify alternate labeling and then
151 use restorecon to put the labels on disk.
152 semanage fcontext -a -t bluetooth_helper_tmpfs_t '/srv/myblue‐
154 tooth_helper_content(/.*)?'
155 restorecon -R -v /srv/mybluetooth_helper_content
156 Note: SELinux often uses regular expressions to specify labels that
158 match multiple files.
159 The following file types are defined for bluetooth_helper:
161 bluetooth_helper_exec_t
165 - Set files with the bluetooth_helper_exec_t type, if you want to tran‐
167 sition an executable to the bluetooth_helper_t domain.
168 bluetooth_helper_tmp_t
172 - Set files with the bluetooth_helper_tmp_t type, if you want to store
174 bluetooth helper temporary files in the /tmp directories.
175 bluetooth_helper_tmpfs_t
179 - Set files with the bluetooth_helper_tmpfs_t type, if you want to
181 store bluetooth helper files on a tmpfs file system.
182 Note: File context can be temporarily modified with the chcon command.
186 If you want to permanently change the file context you need to use the
187 semanage fcontext command. This will modify the SELinux labeling data‐
188 base. You will need to use restorecon to apply the labels.
189
192 semanage fcontext can also be used to manipulate default file context
193 mappings.
194 semanage permissive can also be used to manipulate whether or not a
196 process type is permissive.
197 semanage module can also be used to enable/disable/install/remove pol‐
199 icy modules.
200 semanage boolean can also be used to manipulate the booleans
202 system-config-selinux is a GUI tool available to customize SELinux pol‐
205 icy settings.
